FOUNDATION Russian patent published in 2022 - IPC E02D27/34 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in the construction of foundations in industrial and civil engineering in seismic areas. The foundation includes a round shell filled with bulk material and a shoe installed on the bulk material, the contour of which repeats the contour of the shell, a short pile vertically placed in the bulk material, having a sharp end, and the lower surface of the support shoe has a curvilinear bulge with a central recess, into which the upper the end of a short pile, the transverse dimensions of the support shoe in the plan are 0.63-0.85 of the inner diameter of the shell, and the height of the curvilinear part of the shoe is 0.1-0.25 of the shoe diameter. The shell is made of rubber-reinforced material in the form of a horseshoe-shaped body of revolution. The curvilinear bulge of the shoe is made in its central part in the form of a protrusion with a diameter equal to the diameter of the shell opening and a height not less than the height of the wall of the shell hole, and the extreme round flat flange of the shoe rests on the upper horizontal wall of the shell. The pile and the central recess of the shoe in the plan are made in the form of an equilateral triangle. The shell is made of a metal-cord utilized tire of a heavy-duty vehicle.

EFFECT: ensuring an increase in the stability of the foundation to seismic and eccentric loads, reducing the cost and simplifying the manufacture of the foundation.
